Flexible spectral imaging color enhancement in colon capsule endoscopy: Scoping review of evidence for lesion detection and characterization.
Review in Endoscopy international open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and study aims: Second-generation colon capsule endoscopy (CCE) has achieved high diagnostic accuracy for polyp detection. However, its widespread adoption as a filter test is hampered by major cost-effectiveness concerns, due to significant follow-up endoscopy rates (FER), quantified as high as 42%, thus revealing a potential paradox: CCE superior detection of un-characterized lesions may worsen the economic problem. Flexible spectral imaging color enhancement (FICE) is a standard virtual chromoendoscopy tool, but its role in CCE has been considered uncertain. This scoping review aimed to evaluate available evidence on FICE in addressing CCE limitations in lesion detection and characterization. Methods: A systematic literature search identified studies investigating use of FICE in CCE, focusing on studies analyzing FICE performance in improving detection rates and differentiating polyp histology. Results: Two key studies representing complementary evidence were analyzed. Regarding detection, a prospective trial demonstrated that FICE significantly improved overall per-lesion sensitivity compared with white light (WL) (79% vs. 61%). Specifically, FICE outperformed WL for 6-9-mm polyps (93% vs. 65%), flat/non-protruding lesions (75% vs. 53%), and serrated polyps (74% vs. 57%). Regarding characterization, a quantitative colorimetric analysis identified that the color difference between polyps and mucosa in FICE reliably discriminates histology, yielding a 0.928 area-under-the-curve (AUC), with 91.2% sensitivity and 88.2% specificity. Conclusions: FICE may play a complementary role in CCE, significantly improving detection of high-risk flat/serrated lesions and providing objective data for differentiating adenomas from hyperplastic polyps. Integrating FICE into diagnostic workflows could provide a smart solution to address CCE high FER and cost-effectiveness barriers.
